Investors Just Pulled Money Out of Big Stock Funds at a Pace Not Seen Since December

Keypoints:

• US investors recorded net sales of $32.27 billion in equity funds for the week of September 11
• That's the largest weekly outflow since $52.45 billion in disposals in mid-December 2025
• Large-cap funds alone posted record weekly outflows of $40.44 billion
• Traders priced in about a 90% chance of a Federal Reserve rate hike next week, up from 70%
• The S&P 500, Dow, and Nasdaq all posted weekly declines despite rebounding Friday

US investors pulled a striking amount of money out of stock funds this week, with net equity fund sales hitting $32.27 billion, the largest weekly outflow since a $52.45 billion pullback in mid-December 2025, according to LSEG Lipper data. Large-cap funds bore the brunt of it, posting record weekly outflows of $40.44 billion on their own.

The trigger traces back to a shifting Federal Reserve outlook. A hotter-than-expected inflation reading pushed traders to price in roughly a 90% chance of a Fed rate hike at next week's meeting, sharply up from about 70% just a day earlier. Higher rate expectations typically make holding stocks less attractive relative to safer, higher-yielding alternatives, which helps explain why money moved out of equity funds so quickly.

The major indexes felt the pressure through the week even as Friday brought some relief. The S&P 500 fell 0.8% for the week, the Dow dropped 1.6%, and the Nasdaq slipped 0.7%, snapping a run of gains. All three indexes rebounded Friday alone, with the Dow climbing more than 500 points as oil prices retreated and traders looked past the inflation data for one session.

Mid-cap funds told a different story than large caps, posting a far smaller net outflow of just $682 million, suggesting the sharpest reaction was concentrated in the biggest, most widely held names rather than spread evenly across the market. With the Fed's decision now the central focus heading into next week, this week's fund flows offer an early read on just how nervous investors have gotten about what the central bank does next.
